I've not seen an answer to this in any forum. I make a call through Asterisk, with a VOIP phone, doesn't matter which. The call gets made, I leave a voicemail, or complete the call in some manner, and the other side hangs up. I hear a busy signal on the phone on my end. If I have an extension that looks like this, after the hangup() is executed, my phone gives busy signals until I

Hello, how can I get the similarity value (i.e., the inner cluster similarity) that was used to cut a hierarchical tree at a specific height? I would appreciate your help! Best regards, Madeleine

This worked for me with your example: source("dumpdata.R") storage.mode(x.hc$merge) <- "integer" plot(x.hc) (R-1.4.1 compiled from source on WinNT4.)

I've been trying to get plot.hclust to work with a hclust object I created and have not had much success. It seems that there is some "hidden" characteristic of a hclust object that I can't see. This is most easily seen in the following example, where plot.hclust works on one object, but when this object is "...

Add usb-ver format check to "usb-hc-create". In original file, "usb-hc-create" allows usb-ver parameter as "2/2.0/2.0aaa". In low level hc create, it only uses the integer part (that is "2"), so there is no problem. But 2/2.0/2.0aaa will be saved into VM config. After that, while doing "usb-l...

Hello. I run samba 3.0.21c on RHEL AS 4 EMT_64 U3 and I've experienced a strange problem where smbd will go (and stay) in the D state. While waiting for IO (possibly), these smbd processes do not respond to client requests, thus samba appears to be down. I could not kill these processes via kill -9 , so I rebooted which worked. The only error I could see out of the ordinary would be

Buenas tardes a todos, Estoy interesado en cambiar los límites del eje y en un dendograma construído utilizando la función hclust(). A continuación un ejemplo: hc <- hclust(dist(USArrests), "ave") plot(hc) Hasta aquí todo bien. Si quisiera cambiar los límites del eje "y" de c(0, 200)? Al usar plot(hc, ylim = c(0, 200)) no observo efecto alguno. Qué puedo hacer? Muchas gracias a todos. Jorg...

Can anyone explain this behavior? Essentially, I've created a short file to be read in via source() that gets some descriptive information on a series of variables in a data frame. For each variable, I do three things: print('last.hc.actors') quantile(last.hc.actors,probs=seq(0,1,0.1),na.rm=T) stem(last.hc.actors) where the variable name is (in this case) last.hc.actors. All that is fine, except that R seems to quietly ignore all the quantile() steps. I narrowed it down to bare minimum, trying with a file, test.R, that c...
